Do you have the pam package that's part of the Planet CCRMA repository? 
These latest kernels need it for you to be able to use realtime 
scheduling as a normal user (non-root). If you installed the
planetccrma-core-edge package the proper pam should be there...

Those priorities are not the ones used by the CCRMA packages (which are
changed to work best with the priorities chosen by the rtirq startup
script)
